NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 577,751, dated February23, 1897.

Application filed June 1,1896. Serial No. 593,857. (No model.)

To LZZ whom t may concern.-

Be it known that I, JAMES EHINES, residing near I'Iinesville, county ofLiberty, State of Georgia, have invented a certain new and usefulImproved NutLock, of which the following is a specification7 referencebeing had to the accompanying drawings.

The object of my invention is to produce an improved spring-washernut-lock of that class in which the nuts carried upon adjacent bolts aresecured bya single washer, the particular features of which will appearfrom the subsequent specification and claim.

In the accompanying drawings, Figure Iis a side elevation of abuttingsections of rails combined with a fish-plate, bolts, nuts, and mylocking device. Fig. II is a longitudinal section of the same, takenjust above the nutlock. Fig. III is a side elevation of my nut* lockdetached. Eig. IV is a view of a portion of plate from which my lock isformed and before it is bent.

Referring to the figures on the drawings, 1 and 2 indicate,respectively, abutting sections of rails.

3 indicates a fish-plate, l and 5 bolts for securing the parts togetherin the usual manner, and 6 and 7 the nuts upon the respective rails.

8 indicates the body part of my nut-lock, which consists of a bowedspring-plate that is in practice designed to be placed with its bowedmetal part against the iish-plate or like support. Each end is providedwith boltholes 9 and lO, respectively, which should be alittle largerthan the bolts which they are designed to receive in order to allow playof the spring. Each end is beveled, as indicated by the line a in Eig.II, so as to present a top surface ll squarely against the bottom of thenut when it is turnedidown to meet the beveled face of the lock. Eachface l1 is provided with a series of radial teeth 12, over which the nutturns readily in one direction, and which cut into the bottom of the nutto prevent its backward movement.

By the device above described the nut when screwed against the lock isat all times in engagement with the teeth and may be locked in anyrequired position upon its bolt.

A nut-lock consisting of `a `spring-plate bowed toward the fish-plateand having the faces of its apertured end sections inclined from thebody portion and formed with teeth, whereby the ends will abut squarelyagainst the bases of the superimposed nuts, substan.- tially as setforth.

In testimony of all which I have hereunto subscribed my name.

JAMES E. HINES.
